Create an SSH key and connect from Windows, Mac or Linux

What a key is

An SSH key is a pair of files: a private key that stays on your computer (never share it) and a public key you give to us. We never accept passwords for SSH — only keys — which stops password-guessing attacks.

1. Create the key (Windows PowerShell, Mac or Linux Terminal)

Press Enter to accept the default file; type a passphrase if you want an extra lock.

ssh-keygen -t ed25519 -C "[email protected]"

2. Copy the public key

# Mac
pbcopy < ~/.ssh/id_ed25519.pub
# Windows PowerShell
Get-Content $env:USERPROFILE\.ssh\id_ed25519.pub | Set-Clipboard
# Linux
cat ~/.ssh/id_ed25519.pub

3. Add it in the dashboard

Open SSH and SFTP, press Turn SSH on, then Add a key and paste. (No terminal? Use Generate and download instead: your browser saves a .pem private key — we keep no copy — and you use it with -i below.) The page shows your username and the server address.

4. Connect

ssh [email protected]
# with a downloaded key:
ssh -i ~/Downloads/your-key.pem [email protected]

Make it shorter (optional)

Add this to ~/.ssh/config on your computer, then simply type ssh cloudninza:

Host cloudninza
  HostName server1.cloudninza.com
  User USERNAME
  IdentityFile ~/.ssh/id_ed25519

Copy files with SFTP

From the terminal, or with FileZilla (Settings → SFTP → Add key file, then host sftp://server1.cloudninza.com, port 22, your username):

sftp cloudninza
put site.zip web/yourdomain.com/public_html/
get web/yourdomain.com/app/.env.example
exit

Where you are after connecting

You land in your account's home folder inside a private sandbox: web/yourdomain.com/public_html for PHP and WordPress, web/yourdomain.com/app for Node.js, Python and Java. Nothing belonging to other customers is visible.
